Polish Minister of Foreign Affairs Radosław Sikorski during his two-day visit in Ukraine that began Thursday met with the country’s Prime Minister Arseniy Yatsenyuk to discuss the transit of Russian natural gas, the EU-Ukraine Association Agreement, the May presidential elections, and the visa-free travel between Poland and Ukraine.

On Friday, speaking to the press about the unresolved issue of the supply of Russian gas to Ukraine, Sikorski said that the Polish government was ready to host gas talks between Kiev and Moscow.

„The most pressing issue right now is for Russia and Ukraine to reach an agreement on natural gas. Both countries need each other: Ukraine needs Russian gas and Russia needs Ukrainian storage facilities to be able to transport gas further west to the European Union”, Sikorski said.

The minister added that there was very little time left to sign a new deal. ”For Russia to be able to export its gas to the EU, the storage facilities have to be filled up in June”, he said.

In April President Vladimir Putin warned in a letter to 18 European heads of states that Gazprom might stop gas deliveries if Ukraine fails to pay its debt to Russia.

The first trilateral talks between Russia, Ukraine and the EUthat took place on May 2 in Warsaw have failed.
